About ICD-9-CM 332.1
332.1 is an ICD-9-CM diagnosis code for secondary parkinsonism. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 3 ICD-10-CM codes, such as G21.11 (Neuroleptic induced parkinsonism), G21.19 (Other drug induced secondary parkinsonism) and G21.8 (Other secondary parkinsonism). All of these are approximate matches, so review the record to pick the right one.
